Abstract
The invention discloses the antitorque balance pier of a kind of swivel bridges mobile load, comprising: there is the plummer of foundation pile, tumbler, main pier stud, king-tower, balance pier stud, compensation tower and balance drag-line; Described main pier stud is fixed on plummer centre by tumbler, is provided with a pair balance pier stud at main pier stud Bilateral Symmetry, is horizontal girder and vertical king-tower at main pier stud top, and the girder two ends being positioned at king-tower bilateral are arranged with a pair compensation tower equally; When girder turn balance pier stud overlap with compensation tower time, by affixed for the compensation tower lower end balanced on pier stud top and girder; Balance drag-line is separately fixed at king-tower and compensation tower is longitudinal.The present invention can solve the technical problem of the antitorque balanced adjustment of mobile load of horizontal ultra-wide degree bridge.
Description
Technical field
The invention belongs to the antitorque balancing technique of swivel bridges mobile load in bridge construction.In particular to the device of the antitorque balanced adjustment of bridge mobile load of turning of large span, ultra-wide degree.
Prior art
Existing highway bridge construction turning technology is mainly flat turn method.The swing system of flat turn method is turned primarily of rotating support, is rotated traction and equilibrium system composition.For the domestic many employing counterweight forms of construction work of equilibrium system, good bridge system is had no for horizontal ultra-wide bridge and addresses this problem.
Summary of the invention
The object of this invention is to provide the antitorque balance pier of a kind of swivel bridges mobile load, to solve the technical problem of the antitorque balanced adjustment of mobile load of horizontal ultra-wide degree bridge.
In order to realize foregoing invention object, the technical scheme that the utility model adopts is as follows:
The antitorque balance pier of swivel bridges mobile load, comprising: have the plummer of foundation pile, tumbler, main pier stud, king-tower, balance pier stud, compensation tower and balance drag-line; Described main pier stud is fixed on plummer centre by tumbler, is provided with a pair balance pier stud at main pier stud Bilateral Symmetry, is horizontal girder and vertical king-tower at main pier stud top, and the girder two ends being positioned at king-tower bilateral are arranged with a pair compensation tower equally; When girder turn balance pier stud overlap with compensation tower time, by affixed for the compensation tower lower end balanced on pier stud top and girder; Balance drag-line is separately fixed at king-tower and compensation tower is longitudinal.
A pair balance pier stud as above is located at main pier stud bilateral with outward-dipping direction symmetry.
A pair compensation tower as above is located at girder bilateral with outward-dipping direction symmetry.
The antitorque balance pier of swivel bridges mobile load as above, the compensation tower of king-tower and bilateral is provided with the fixing hole of connection balance drag-line between the two.
Advantage of the present invention completes mobile load antitorque balance pier (tower) structure technology by turn pier (tower) and main beam structure of dead load, the unbalance stress of adjustment direction across bridge, the lower pier stud of pier (tower) simultaneously, can as the interim stretch-draw pier of turning, making turns itself arranges no longer separately interim stretch-draw pier.Ensure supplementing rotator construction technique, guarantee bearing capacity and the Stability Analysis of Structures of overall bridge construction load, significantly improve Long span, ultra-wide degree swivel bridges mobile load overturning or slip resistance analysis coefficient and to reduce drag-line face stress amplitude and anchor head tired.

Detailed description of the invention
Structure of the present invention is see Fig. 1,2.The antitorque balance pier of described swivel bridges mobile load, comprising: have the plummer 5 of foundation pile, tumbler 7, main pier stud 1, king-tower 12, left-right balance pier stud 8,3, left-right balance tower 10,14 and balance drag-line (main drag-line) 16; Described main pier stud 1 is fixed on plummer 5 centre by tumbler 7, a pair outward-dipping balance pier stud 8,3 is provided with at main pier stud 1 Bilateral Symmetry, be horizontal girder 9 and vertical king-tower 12 at main pier stud 1 top, the girder two ends being positioned at king-tower 12 bilateral are arranged with outward-dipping a pair compensation tower 10,14 equally; When girder 9 turn balance pier stud 8,3 overlap with compensation tower 10,14 time, by affixed for compensation tower 10,14 lower end balanced on pier stud 8,3 top and girder 9; Balance drag-line 16 is separately fixed at king-tower 12 and compensation tower 10,14 is longitudinal.The compensation tower 10,14 of king-tower 12 and bilateral is provided with the fixing hole of connection interim balance drag-line 11,12 between the two.
Concrete construction sequence is as follows:
1), substructure construction
Then first construction stake basis is cushion cap, pre-buried main pier stud tumbler in cushion cap, then carries out main pier stud and the construction of balance pier stud.
2), main girder construction, simultaneously installation king-tower and king-tower suspension cable.
Main pier stud first to be constructed king-tower, then cantilever casting construction girder, main drag-line is installed simultaneously.
3), compensation tower of constructing, add interim rope, both sides compensation tower carries out simultaneously.
At girder horizontal correspondence position construction compensation tower, add interim rope simultaneously, prevent compensation tower from tilting, require that both sides compensation tower is constructed simultaneously.
4), cable stayed bridge is turned.
See Fig. 3,4,5, utilize balance pier stud to rotate device, superstructure is turned, turn to along alignment direction (becoming bridge location to put).
5), connect compensation tower and balance pier stud, make both consolidation be integrated.
Until superstructure complete in place after, complete compensation tower and balance pier stud consolidation, make both be connected as a single entity.
6), PHT (compensation tower) drag-line is installed, removes interim rope (king-tower does not show).
Compensation tower drag-line is installed, removes the interim rope of compensation tower.
7), closure segment in the middle of construction.
See Fig. 6, after realizing respectively turning until two sections of turning, compensation tower drag-line being installed, two section of turning girders are connected.
8), remove falsework, unification is built deck paving and is put into effect.
